Other metabolic pathways of cellular respiration include oxidative decarboxylation of pyruvate (which is when pyruvates are oxidized to acetyl-CoA and CO2), Citric Acid Cycle (also known as the Kreb Cycle), and oxidative phosphorylation, with the latter producing water as a waste product. Working Scholars® Bringing Tuition-Free College to the Community. The bloodstream delivers oxygen to cells and removes waste carbon dioxide through internal respiration, another key function of the respiratory system. The CO2 then binds with water molecules to produce carbonic acid. This lactic acid then builds up and causes discomfort to our bodies and is the pain many athletes feel in their muscles when they exert themselves too much. The main function of the cellular respiration is hydrogen and its bonding electrons change partners.Carbohydrates, fats and proteins are all consumed as fuel in cellular respiration. 2. Answer. Cellular respiration 25. The overall reaction is broken into many smaller ones when it occurs in the body, most of which are redox reactions themselves. Cellular respiration is a process by which cells harvest the energy stored in food. 1 decade ago. D. NADH. The main function of cellular respiration is _____. When this happens, pyruvates aren’t transported from the mitochondrion; instead, they remain in the cytoplasm, where they ferment and release lactic acid. Create your account. NADH contributes to oxidation in cell processes like glycolysis to help with the oxidation of glucose. In higher organisms like mammals, fermentation usually occurs during strenuous activities like exercise. Also know, what is the function of NADH?
